Your vaccine guide to list of possible ‘side-effects’

The next phase of the Covid-19 vaccination campaign for citizens over 45 years of age begins tomorrow, April 1, 2021. Eligible citizens can book their place either online or offline. The central government had announced that citizens who are eligible for the vaccine can register via the Co-WIN portal or the Aarogya Setu app. A user can register four family members (including yourself) for the Covid-19 vaccine.
